Claims

[Scope of utility model registration request]

A vibrator consisting of a piezoelectric element attached to an elastic body is placed on a base and tilted in the circumferential direction, and a bowl is connected to the upper end of the vibrator to vibrate, wherein the vibrator and the bowl are connected to each other. A piezoelectric drive bowl-shaped parts feeder characterized in that the piezoelectrically driven bowl-shaped parts feeder is connectable via a mounting plate which can be divided into parts corresponding to each vibrating body and has holes provided corresponding to the mounting positions of each vibrating body.
